I applied for an internal transfer to product management at a FAANG after a part time rotation for 6 months and interview prepping with PMs throughout. I was rejected without any feedback and told to find a full time 6 month rotation before trying again. But convincing your manager to pay for you when you won’t be doing your job for 6 months is a very difficult sell. And there’s no guarantee you will get the job if your performance is strong since you still need to pass the interviews.

I applied out and had multiple offers a couple months later. It’s a shame really, wanted to stay and felt I had a lot more to contribute and learn but was concerned that I would just stagnate in the interim.
